Here's a cool design for math and art nerds. The mathematical constant Pi visualized as colored circless in a 30 x 30 grid. Each digit is a different color. That's 900 digits of Pi (minus 1 for the Pi symbol at the end of the list). Perfect for Pi Day or just because it's cool to look at. A colorful visualized Pi T-shirt, hoodie, bag or other fun merchandise makes a great geek gift!
